Kourtney wants us all to know that KhloMoney is doing great.

Khloe had to cancel a bunch of book signings after recently being diagnosed with staph infection, which had tons of fans worried. While on the red carpet at the Variety & Women’s Wear Daily luncheon, Kourtney revealed, “She’s good. She’s OK. She’s not feeling well, but she’s OK.”

A source close to the family confirmed that KhloMoney’s health is on the incline, telling PEOPLE she’s “home on antibiotics and being closely monitored by a doctor.”

Although fans were disappointed that the Strong Looks Better Naked author had to cancel a few signings, her two adorable No. 1 fans showed major love. Khloe shared the cute photo above of her nieces North West and Penelope Disickholding up a copy of her book, writing, “They were so excited and kept screaming ‘KoKo!’ ‘KoKo!’ North calls me ‘KoKo Loco.”
